Light Reduction Control

Sequence of Operation

  1. Lighting (a) auto On for 50% illumination when occupancy detected.
  2. Manual On/Off and 50% reduction control of lighting (a, b) with wall switch.
  3. Auto Off all lighting within 20 minutes of occupants leaving.

Design Considerations

  1. When lighting power in the primary sidelight area is over 150 W, it must have automatic daylight responsive controls installed for all general lighting in that area.
  2. Although not required by IECC, receptacle control can be added to this space for additional energy savings.
  3. If dimming is desired, use an DCLV2 dimming wall switch and dimmable fixtures, replacing the LVSW-102 2-button wall switch. If detection coverage is sufficient with a wall box dimming occupancy sensor, a DW-311 or PW-311 can also be used.
  4. Time scheduling, demand response and remote programming/diagnostic functions are available using Wattstopper Digital Lighting Management networked products.
  5. To integrate occupancy detection control with the HVAC system, use a DT-300 occupancy sensor with isolated relay.
